Berries Protect Your Brain

Strawberries are good for your brain, according to breaking news out of the 2009 Berry Health Symposium. Several of the latest studies, conducted by world-renowned researchers, consistently showed that strawberry consumption is a simple way to improve cognitive function.

For example, one study presented by researchers from the Chicago Healthy Aging Project (CHAP) showed that older adults who consume strawberries at least once per month have less cognitive decline. More specifically, women who consumed more than one serving of strawberries per month had a 16.2% slower rate of cognitive decline versus those who consumed less.

With increasing age, brain function diminishes. This has been conclusively shown in laboratory studies, by Drs. James Joseph and Barbara Shukitt-Hale of USDA Agricultural Research Service at Tufts University. Their latest research at the conference demonstrated that aging results in deficits in learning, memory and motor function, such as balance and walking speed - and concluded that strawberries and other berries improved both memory and motor function.

Berries Can Preserve Brain Function

So what is it about berries that seem to protect the brain?

Researchers from the 2009 Berry Health Symposium took a stab at answering that very question. Most disease processes in the body are believed to begin through inflammation and oxidation, two of the very processes I focus on in my forthcoming book "The Most Effective Ways to Live Longer". Both inflammation and oxidation damage cells. Healthy nerve cell membranes promote optimal communication within the brain and nervous system so preventing membrane damage from inflammation and oxidation is essential.

Since berries- and other fruits and vegetables- contain a ton of antioxidants and anti-inflammatories, it's easy to connect the dots and see why they might preserve brain function.

Prevention of Dementia in an Aging Population

Dementia is the loss of cognitive function of sufficient severity to interfere with everyday tasks. Alzheimer's disease is the most common form of dementia. It is estimated that one in eight persons, aged 65 and older have Alzheimer's. There is no cure for the disease and treatments are ineffective.

According to recently released census estimates, the world's 65-and-older population will triple by 2050 to make up 1 in 6 people. The number of senior citizens has already increased 23 percent since 2000 to 516 million, more than double the growth rate for the general population. As a result, the incidence of dementia is likely to rise.

The frequent consumption of berries is emerging as a potential simple dietary factor for prevention.

California strawberries are grown and available year-round in supermarkets across the country. Do remember- the Environmental Working Group lists strawberries as one of their "Dirty Dozen" (i.e. most contaminated crops). So when you do buy strawberries from the supermarket, be sure to get organic!

Fast Food Diet May Raise Alzheimer's Risk

Guest article by Craig Weatherby

An estimated 5.2 million Americans suffer from Alzheimer's disease, and the toll it takes on their families may well exceed the patients' own suffering.

The results of a study from Sweden heighten suspicions that diets dominated by junky fast food meals damages brains, in addition to harming heart and overall health.

By "fast food meals" we mean ones high in sugars, starches, and bad fat but low in colorful, fiber- and antioxidant-rich plant foods. Sugary, starchy foods tend to promote generation of pro-oxidant, pro-inflammatory free radicals, as do fried and browned foods. The damage done to brain (and other) cells by free radicals and the inflammation they induce raise the risk of Alzheimer's.

Population studies link diets rich in antioxidants (and omega-3s) to reduced rates of Alzheimer's, and studies in dogs with Alzheimer's-like disease show clear improvements after increasing their intake of dietary antioxidants.

There's a genetic component to Alzheimer's though it's far from the whole story.

About one in five Americans possesses a gene that raises their risk of developing Alzheimer's disease ... which is by far the most common form of dementia. The risky gene, called apoE4, is a variant of the gene that governs the production of a cholesterol-transport protein called apolipoprotein E. People who carry the apoE4 gene are more likely to develop the brain abnormalities characteristic of Alzheimer's disease, and to later show symptoms of Alzheimer's.

But once again, genes "load the gun" but environment pulls the trigger.

A doctoral student at Stockholm's famed Karolinska Institute tested the effects of fast-food-like diets in mice genetically at risk for Alzheimer's- these mice had been specifically bred to carry the risky apoE4 variant of the apolipoprotein E gene. Researcher Susanne Akterin fed the Alzheimer's-prone mice a simulated fast-food diet for nine months.The mice developed brain abnormalities like those seen in Alzheimer's patients.

The moral of the story: You can't do much about your genes, but you can sure increase the odds of keeping your brain healthy by staying away from fast food and making sure you stock up on antioxidants.
